Identify the rhyme scheme of the stanza of the following poem. from "anabelle lee" by edgar alan poe: "it was many and many a year ago, in a kingdom by the sea, that a maiden there lived whom you may know by the name of annabel lee; and this maiden she lived with no other thought than to love and be loved by me." abcabc aabaac ababab ababcb

ABABCB
The ending rhymes are:
ago
sea
know 
Lee
thought
me

You assign the letter A to the word at the end of the first line, and then each different rhyme moves to the next letter of the alphabet. You assign the same letter to lines that rhyme.

Line 1, "ago" gets an A and since Line 3 "know" rhymes with that, it also gets an A. 
Line 2 "sea" does not rhyme with line 1 so it gets a B. The following lines 4 and 6 "Lee" and "me" rhyme with line 2 so they also get Bs.
Line 5 "thought" does not rhyme with anything in the lines above it, so that is why it gets a C.
